Residential Land: Land characterized by presence of a residence. Residential land was demarcated as the smallest area containing the central residence and any outbuildings. Typically this area would include a portion of lawn and driveway around the residence.
	Commercial/Municipal land: Land characterized by structures of size and situation uncommon to residential lands and also by the availability of parking often associated with commercial operations.  Commercial land was designated to include the smallest land area that encompassed all of the buildings, parking areas and other areas of identifiable impervious surfaces.  Municipal land was characterized by a large central structure, parking areas and recreational areas.  Schools were demarcated to include only the impervious land; recreational fields were marked as grassland.
